MRC asset standards
MRC-20, MRC721, MRC1155, and MRC4626 are design and implementation names, not an active public economic contract. This page does not certify a module address, asset catalog, call schema, authority rule, mint, transfer, approval, burn, deposit, withdrawal, preview, wallet, SDK-write, RPC, or submission flow.
The intended categories are fungible assets, non-fungible collections, mixed multi-assets, and tokenized vaults. A source type, native-module enum, reserved address, SDK encoder, or historical example is not proof that a write is deployed, enabled at the active genesis, audited, rendered by wallets, or safe for value.
Before publishing an actionable integration, the project must provide mutually consistent runtime, genesis, activation, SDK, RPC, receipt, indexer, wallet-review, authority, fee, audit, and end-to-end evidence. Until then, do not construct calls, create assets, quote balances as redeemable, or use real funds.
